Last fall I wrote about Fate of the World, a new video game in development at the time that asked players to figure out how to avoid the worst fates of climate change and secure a livable future for our planet's citizens.

The game is available today. (For PC only, alas. The Mac version is still under construction.) Better still, if you buy it before Thursday, March 3rd, all proceeds will benefit TckTckTck, a very important global coalition of NGOs working together to combat climate change.

Fate of the World is a dramatic global strategy game that puts all our futures in your hands. The game features a dramatic set of scenarios based on the latest science covering the next 200 years. You must manage a balancing act of protecting the Earth's resources and climate versus the needs of an ever-growing world population, who are demanding ever more food, power, and living space. Will you help the whole planet or will you be an agent of destruction?

Last time I wrote about the game, I said I wouldn't be playing it. ("Not because I'm too good or too cool for them or because I think they rot brains and cause diabetes or anything like that. But rather because I know from limited experience as a child obsessively playing Kings Quest, SimCity, and Shadow President that if I were to dip my toes into the waters of Civilization or Spore or any of these other awesome simulation games, I would immediately be threatening my sleep, health, sanity, and relationship.) But now I'm rethinking. When else will have have the chance to have a professional excuse to play video games? I'll have a thorough review if and when I do.

Also, this game seems like an evolution—or at least branch—of simulation gaming "for good," or how video games could actually make the world a better place. Jane McGonigal gave a pretty convincing, if somewhat controversial, TED talk about exactly that last year, which is well worth watching in the context of Fate of the World.
